Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2015 Chevrolet Suburban Owner Comments

  • 54,000 miles


I am writing about my 2015 Chevy Suburban. I own a limousine service and use the Suburban in my fleet. Yesterday a driver, with passengers, had a total failure of the power braking system. It is at a local repair shop now, and I am being told the air pump had broken apart, inside, snapped the fan belt resulting in no vacuum getting to the power brake system. My driver was barely able to stop the vehicle before rear ending another car on the highway. The vehicle has 54,000 miles and I am being told is out of the bumper to bumper warranty. There are also no open recalls. I am reporting this issue to the NHTSA and the Massachusetts attorney general's office, as I believe this is an immediate danger to the general motoring public. I just contacted Chevrolet by phone and email. The representative on the phone said all she could tell me is that it's out of warranty, there were no recalls, and I am basically on my own to repair. I hope you are able to investigate this situation, identify the cause of this failure, and come up with a remedy for the safety of everyone.

A/C no cold air. I went to dealership and they tested and said there's huge hole. Apparently they only said small leak. They replaced with new condenser. I was forced to pay nearly 1,400. Also resurface front disc brake. This is brand new vehicle and over 20 vehicles I know have same issues. There should be recall on this vehicle. I went to dealer and they said deal with GM. I went to GM they won't resolve my issues.

The contact owns a 2015 Chevrolet Suburban. While attempting to brake the vehicle, the brakes made an abnormal loud noise. The vehicle was taken to the dealer where it was diagnosed that the brakes and rotors needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact stated that the brakes and rotors had been replaced a total of three times since the purchase of the vehicle. Also, while attempting to accelerate, the vehicle hesitated and slowed down. The vehicle was taken to the dealer. The contact was informed that the vehicle had not failed and that was how it was calibrated. The contact also stated that the liftgate failed to open automatically and had to be manually operated. The vehicle was taken to the dealer, but the failure could not be duplicated. The manufacturer was made aware of the failures. The failure mileage was 43,000.

While driving on a highway, the ABS & brake warning lights eliminated. It was determined that the issue was the ebcm brake controller module that had failed causing the associated ABS brake pump to run continuously, thus destroying it. The module and pump are located on the frame approx. Below the drivers set. Dealer's estimated cost to repair $1,200. At the time of the incident the ebcm module was on back order and the dealer could not correct the issue. I had to buy a refurbished module and a new pump to solve the issue.

\the accelerator pedal and brake pedal are separated by 1-1/4 inches. At rest, the brake pedal is about 1/2 inch higher than the accelerator pedal. When depressed, the brake pedal is 1 inch lower. It is very easy to move your right foot from the accelerator to depress the brakes and not be far enough over to avoid also depressing the accelerator at the same time. There is 4 inches of space between the accelerator pedal and side of the car body on the right side. This is plenty of room to relocate the accelerator pedal to the right, perhaps so that there is the width of a man's shoe sole between the two pedals.
